  • Patent number: 7934898
    Abstract: A wafer processing system has a wafer loading system accommodating sufficient wafer carriers to substantially maximize the processing speed capability of the processing system. Wafer carriers are placed into and removed from the loading system by one or two overhead carrier loading tracks. Carriers may be loaded or removed while other carriers are in work. One or more transfer robots may move wafers from the carriers to buffers. One or more process robots in a process module move wafers from buffers, or other locations, to processors in the process module.

  • Publication number: 20090022574
    Abstract: A wafer loading system accommodates sufficient wafer carriers to substantially maximize the processing speed capability of wafer processing systems. Wafer carriers are placed into and removed from the loading system by one or two overhead carrier loading elements, such as overhead track systems. Carriers may be loaded or removed while other carriers are in work. One or more transfer robots may move wafers from the carriers to buffers. Methods of operating the loading system allow delivery and removal of wafers to and from the processing systems to meet or exceed the processing speeds of the processing systems.

  • Patent number: 7294243
    Abstract: Contact assemblies for electrochemical processing of microelectronic workpieces. The contact assembly (400) can comprise a support member (410) that includes an inner wall (412) which defines an opening (414) configured to receive the workpiece and a plurality of contacts (420). The individual contacts (420) include a conductor (440) and a cover (430). The conductor (440) can comprise a proximal section (435) projecting inwardly into the opening (414) relative to the support member (410), a distal section (436) extending from the proximal section (435), and an inert exterior (444) at least at the distal section (436). The cover (430) comprises a dielectric element that covers at least the proximal section of the conductor, but does not cover at least a portion of the distal section of the core. The exposed portion of the distal section of the core, accordingly, defines a conductive contact site for contacting a conductive layer (e.g., a seed layer) on the workpiece.

  • Patent number: 7161689
    Abstract: A processing apparatus for processing a microelectronic workpiece includes a metrology unit and a control, signal-connected to the metrology unit. The control can modify a process recipe or a process sequence of the processing apparatus based on a feed forward or a feed back signal from the metrology unit. A seed layer deposition tool, a process layer electrochemical deposition tool, and a chemical mechanical polishing tool, arranged for sequential processing of a workpiece, can be controlled as an integrated system using one or more metrology units. A metrology unit can be located at each tool to measure workpiece parameters. Each of the metrology units can be used as a feed forward control and/or a feed back control at each of the tools.

  • Patent number: 7102763
    Abstract: A method and apparatus for processing a microelectronic workpiece using metrology. The apparatus can include one or more processing or transport units, a metrology unit, and a control unit coupled to the metrology unit and at least one of the processing or transport units. The control unit can modify a process recipe or a process sequence of the processing unit based on a feed forward or a feed back signal from the metrology unit. The control unit can also provide instructions to the transport unit to move the workpiece to a selected processing unit. The processing unit can include, inter alia, a seed layer deposition unit, a process layer electrochemical deposition unit, a seed layer enhancement unit, a chemical mechanical polishing unit, and/or an annealing chamber arranged for sequential processing of a workpiece. The processing units can be controlled as an integrated system using one or more metrology units, or a separate metrology unit can provide input to the processing units.

  • Patent number: 6921467
    Abstract: Processing tools, components of tools, and methods of making and using such devices for electrochemical processing of microelectronic workpieces. One aspect of the invention is directed toward reaction vessels for electrochemical processing of microelectronic workpieces, processing stations including such reaction vessels, and methods for using these devices. For example, one embodiment of a reaction vessel includes an outer container having an outer wall, a first outlet configured to introduce a primary fluid flow into the outer container, and at least one second outlet configured to introduce a secondary fluid flow into the outer container separate from the primary fluid flow. The reaction vessel can also include at least one electrode, and it can also have a field shaping unit.

  • Publication number: 20030066752
    Abstract: An electrochemical processing apparatus for processing a microelectronic workpiece includes a metrology unit and a control, signal-connected to the metrology unit. An electrochemical deposition unit provides a space to receive said microelectronic workpiece to deposit a subsequent film layer onto a prior layer, wherein a condition signal from the metrology unit influences the process control of the electrochemical deposition unit. The signal can also be used to transfer the microelectronic workpiece to a layer stripping unit, or a layer enhancement unit, or to a non-compliance station. The apparatus is particularly useful in measuring seed layer thickness and adjusting the operating control of a computational fluid dynamic reactor, which electroplates a process layer onto the seed layer.
